Clinical information was collected at initial hospital stay and AL was created using ten parameters representing the metabolic, inflammatory and vascular systems. No neuroendocrine parameters were available. Length of stay (LOS) at the hospital was collected upon departure from the initial hospitalization, and mortality and dependency (modified Rankin Scale) were collected at 90 days post stroke. Factors independently associated with high AL were examined using a multivariable logistic regression model. Associations between baseline AL and post-stroke outcomes (LOS, mortality, and dependency) were examined using unadjusted and adjusted regression models.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>High AL was associated with longer LOS, and higher mortality and dependency at 90 days.
